Windows Server 2022 Standard introduces advanced multi-layer security, hybrid capabilities with Azure, and a flexible application platform. As part of this release, we are bringing secured-core capabilities to help protect hardware, firmware, and Windows Server OS capabilities against advanced security threats. Secured-core server builds on technologies such as Windows Defender System Guard and Virtualization-based Security to minimize risk from firmware vulnerabilities and advanced malware. The new release also provides secured connectivity that introduces several new capabilities such as faster and more secure encrypted HTTPS connections, industry standard SMB AES 256 encryption and more.
Windows Server 2022 improves hybrid server management with significantly improved VM management, an enhanced event viewer, and many more new capabilities in Windows Admin Center. Furthermore, this release includes significant improvements to Windows containers, such as smaller image sizes for faster download, simplified network policy implementation and containerization tools for .NET applications.
The new security capabilities in Windows Server 2022 combine other security capabilities in Windows Server across multiple areas to provide defense-in-depth protection against advanced threats. Advanced multi-layer security in Windows Server 2022 provides the comprehensive protection that servers need today.
Certified Secured-core server hardware from an OEM partner provides additional security protections that are useful against sophisticated attacks. This can provide increased assurance when handling mission critical data in some of the most data sensitive industries. A Secured-core server uses hardware, firmware, and driver capabilities to enable advanced Windows Server security features. Many of these features are available in Windows Secured-core PCs and are now also available with Secured-core server hardware and Windows Server 2022.

Trusted Platform Module 2.0 (TPM 2.0) secure crypto-processor chips provide a secure, hardware-based store for sensitive cryptographic keys and data, including systems integrity measurements. TPM 2.0 can verify that the server has been started with legitimate code and can be trusted by subsequent code execution. This is known as a hardware root-of-trust and is used by features such as BitLocker drive encryption.
Firmware executes with high privileges and is often invisible to traditional anti-virus solutions, which has led to a rise in the number of firmware-based attacks. Secured-core server processors support measurement and verification of boot processes with Dynamic Root of Trust for Measurement (DRTM) technology and isolation of driver access to memory with Direct Memory Access (DMA) protection.
UEFI secure boot is a security standard that protects your servers from malicious rootkits. Secure boot ensures the server boots only firmware and software trusted by the hardware manufacturer. When the server is started, the firmware checks the signature of each boot component including firmware drivers and the OS. If the signatures are valid, the server boots and the firmware gives control to the OS.
Secured-core servers support virtualization-based security (VBS) and hypervisor-based code integrity (HVCI). VBS uses hardware virtualization features to create and isolate a secure region of memory from the normal operating system, protecting against an entire class of vulnerabilities used in cryptocurrency mining attacks. VBS also allows for the use of Credential Guard, where user credentials and secrets are stored in a virtual container that the operating system cannot access directly.
HVCI uses VBS to significantly strengthen code integrity policy enforcement, including kernel mode integrity that checks all kernel mode drivers and binaries in a virtualized environment before they are started, preventing unsigned drivers or system files from being loaded into system memory.
Kernel Data Protection (KDP) provides read-only memory protection of kernel memory containing non-executable data where memory pages are protected by Hypervisor. KDP protects key structures in the Windows Defender System Guard runtime from being tampered
